Small is happy

One and only: singled out for the special treatment”, The Age, 10/5. This article says that single-child families are increasing (which would seem to conflict with the increasing birth rate?). Having one child is sometimes a deliberate choice, but sometimes because parents are older. Some parents, as featured in the article, have come from large families where they were “lost in the crowd” and conversely want their offspring to have more attention. Small families should be actively encouraged worldwide as this will help reduce population growth – one way would be to provide government benefits for a woman’s first two children, but none after that (those who remarry and want more children would also not receive benefits).

The usual counter-argument is that the old will outnumber the young if this trend continues, and that there won’t be enough tax-paying young people to support previous generations, but it is a demographic trend that governments will just have to deal with. Not all old people are infirm, and they can still make useful contributions to society. Perhaps the idea of a fixed retirement age could be done away with – assuming older people can work in jobs they enjoy.

None of the above is intended to deny that we should plan carefully for the demographics of a population in which the number of older people is steadily rising (as the age-cohorts become more even-sized). But we should remember that the old are in many ways less of a burden than the young. Even in retirement, people are often highly productive, performing a myriad of useful and unpaid services, and deploying the skills and experience of a lifetime. By contrast the young, whether babies or school-age children, are too immature or too busy with their studies to be economically “productive” – and in fact need to be looked after by adults.

This post at the Public Population Forum unfortunately brings racism into the topic – namely an overused assertion that white people are being “outbred” by people of other colors. She makes the mistake of associating skin color with culture, when they are entirely different things. Here’s how I try to express this:

Racism is defined as discriminating against or disliking a person purely because of their skin color and/or ethnicity. As all humans share the same biological makeup and heritage, such a distinction is superficial; skin color and other physical characteristics evolved to adapt to different locations and climates, and are not reflective of a person’s intelligence (or lack of it!). Therefore, on biological terms, such racism is illogical. It comes from a basic suspicion of people who “look different” from those one grew up with; such aversion can be overcome through education and familiarization.

Culture, however, is a different matter; it is not related to human biology. Some cultures are considered more desirable than others to live in, which is why there tends to be high rates of immigration to the former. Some cultures are just odious (e.g. those which regard women as chattels) and deserve to become extinct. Culture is thus not relevant to a person’s race; people of different skin colors who grow up in a particular culture will share the characteristics of that culture.

The countries with high population growth are often those described as “developing”, which happen to be places like Africa, etc. Women in these countries often do not have access to education and family planning, and their role is primarily to reproduce. This is a cultural feature, one that can be overcome when women are given access to such facilities – something that women in First-World countries (USA, UK, Australia, etc.) take for granted. Educated women will often choose to limit their family size, or decide not to have children, as they have control over their fertility.
